Berry isn't the only one eating up her new son. His big sister Nahla, 5, has enjoyed having a brand new sibling.

"She's very serious about her big sister role," Berry revealed. "It's like one of her doll babies came alive. She gets to take care of him, feed him, change his diapers, play with him, dress him up in different clothes like five times a day because she can, so she loves it."

Though she loves spending time with her children, it can be challenging to balance her new TV schedule -- she is starring on CBS's sci-fi thriller Extant -- with her husband Olivier Martinez's new role on ABC's Revenge.

"I watched his premiere," Berry said of Martinez's role as French businessman Pascal LeMarchal. "I'm going to follow his little arc along. I'm very, very proud of him. I'm trying to find the balance. My baby's always with me on the set. I bring my daughter after school. I have a nursery there and a playroom. I try to make it as nice as I can."
